Abstract

An elastomeric article comprising an olefin-block copolymer comprising within a range from 4 to 40 mol % of C4 to C12 α-olefin derived units, the remainder being ethylene-derived units, wherein the melting point temperature (T) is within a range from 92° C. to 120° C., and having an M/Mvalue of less than 2.5. The olefin-block copolymer is desirably generated by combining ethylene, C4 to C12 α-olefins, a single site catalyst, preferably a fluxional catalyst, and an activator. The elastomeric article may be an elastic hygiene garment, especially a garment comprising a waistband, stretch ear panels and/or belly bands.
